Home security features

Before choosing one type of home security system, ask yourself what you want to protect. Do you want a nanny cam for the little ones or monitors to catch leaky pipes? Security systems do more than keep intruders out of your home. They can also communicate with your kids when they get home from school or tell you when that Amazon package arrived.

The right equipment package, payment plan, and features for you depend on what you want to do with your system. In today’s market, there are three main types of security system packages available: home automation, security equipment, and environmental monitoring.

Smart home automation

Smart tech adjusts to your family’s schedule and preferences. Home automation can keep the lights on while you’re out of town or let the dog walker in while you’re out of the house.

Security equipment

Traditional home security devices like burglar alarms, glass break detectors, and outdoor cameras are helpful if you’re worried about issues like intrusion, theft, or vandalism.

Environmental monitoring

Equipment like smoke alarms, pipe freeze detectors, and leak detectors fall into this category. Families with older homes, especially, should look for devices in this category.

Professional vs. self-installation

Security systems have recently adopted cellular technology, making them easier than ever to install without professional help. Naturally, there are pros and cons to self-installed and professionally installed security systems.

Professional installation can come with steep installation fees, but you won’t have to do any of the work. Home security companies like Vivint and ADT send a trained professional to your home for a consultation. You’ll be able to discuss your security priorities, budget, and expectations with a real person. These professionals also offer product package bundling and years of industry experience to put you at ease.

On the other hand, a DIY system like SimpliSafe or Frontpoint comes directly to your door pre-programmed and ready to go. These systems may not have as many bells and whistles as their professionally installed counterparts.

But they’re great for smaller homes that need the basics. Installation for these systems is a breeze since most of the equipment sticks onto your walls, doors, and windows.

To the point

Professionally installed security systems require an installation fee, but you don’t have to lift a finger. Self-installed systems are generally more affordable, but you need to do all the placement and installation yourself.

Smart Home

Security system size

Whether you opt for a DIY or professionally installed system, you’ll need enough equipment to fit your home. For example, the best security systems for apartment dwellers require fewer sensors overall. Professional installers for systems like Vivint can recommend the right sized package and add-ons to fit larger homes.

Just remember to cover all the entrances and exits in your home with a sensor or camera, plus any other equipment to protect kids, pets, or the rest of your family. Even adding sensors to window wells and basement entrances can bring an extra measure of security.

Security system costs

It’s tempting to put the price tag as your top priority, but look for the right equipment first, and the right price will appear. All of our favorite home security systems have different tiers of services and prices, each with their own set of advantages and disadvantages. You can find a great home security system on a budget, but you shouldn’t compromise safety while doing it.

When looking at your budget, prices boil down to a set of one-time and regular fees. Most security systems require a monthly payment for monitoring and a one-time payment for the equipment. You can find systems without a monthly fee like Nest Secure that allow you to monitor your own home, but the initial cost is steeper.

It’s wise to read the fine print before signing onto any security system. Most companies charge for cancellation after a trial period or could add extra fees for moving equipment from house to house.

How much does a security system cost?

You can expect to spend around $32 a month on average for professional monitoring services, though costs range from as low as $5 a month up to $65 a month depender on the provider you choose.

Landline security systems use a home phone connection to link security devices and monitoring together. They aren’t as common anymore because they’re easier to tamper with. But folks in rural areas may find that this is their only option if cell reception is poor where they live.

Broadband security systems connect to the professional monitoring center through your home’s internet connection. So if your home’s Wi-Fi goes out, so does your security system. The good news is it’s harder to tamper with than landline security, making it a little safer. All self-monitored security systems and most DIY security systems use an internet connection.

Cellular services are about as expensive as broadband security systems, but you won’t have to deal with hardwiring or power failures. Your devices can “talk” to each other and the professional monitoring center from your home using cellular uplink. The majority of professionally-monitored security systems use a cellular connection.

Most security system companies allow you to take your system to a new home, but some will charge you to buy new equipment or reinstall new devices.

If you move frequently, self-installed systems are much easier and cheaper to use.

For those on a budget, the short answer is “no, but it helps.” Home automation and smart home devices have a variety of functions (and prices).

From something as simple as a smart outlet that lets you turn lights on and off remotely to more sophisticated equipment like a smart doorbell, it all boils down to what makes your life easier and safer.

Smart home equipment is getting better and more affordable every year, so if you’re building a home security system, it’s not a bad idea to start integrating smart devices now.
